Mike Pence did it by being oily and obsequious. Mike Pompeo was angry and combative. Both apparently had the same objective, however: to position themselves to be the American Maduro by providing unconditional loyalty to Chavez–er, Trump.
The problem with this approach is that it would only work if Trump won in 2020, and was viewed as a success when he left office in 2024. Obviously, that hasn’t happened. So now what? Why would the GOP electorate choose the second rate acolyte of a loser in 2024?
Neither Pence nor Pompeo has the man on golf cart’s gift for owning the libs on Twitter. They have nowhere to go on their own merits. As a result, their hopes have to rest on a Trump comeback in 2024. That is, to put it mildly, a long shot.
